lin PDVIYE Mr-π Κ AU 11 Y O U R C ATA LY ΤIC Ρ ROC ESSES WITH ALCOA A L U M I N A for bigger yields
tor better quality
If y o u want to up-grade your catalytic process yields, or simply reduce losses from contamination and side reactions, you'll find it advantageous to insist o n ALCOA Aluminas for your AI2O3 catalysts and catalyst supports. ALCOA Aluminas are uniform in structure and chemical purity . . . stable at elevated temperatures... have high resistance to erosion and crushing . . . a n d are moderate in cost. Typical conversions for which ALCOA Aluminas are used in clude: Aliphatic hydrocarbons into
aromatics, and dehydrogenation of naphthenic hydrocarbons. ·* A L C O A Activated Alumina is preferred for m a n y reactions be cause of its h i g h adsorptive properties and e x t r e m e l y large surface area·
For t o p quality, specify ALCOA Aluminas for catalysts and cata lyst s u p p o r t s . You'll g e t more efficient, uniform reactions and end-products of higher purity. We'll gladly send y o u samples and further information.
*" ALCOA Tabular and o t h e r forms of A l u m i n a are preferred for certain reactions where hardness and extremely h i g h purity are relatively more i m portant than maxi m u m surface area.
